ILLUMINATING VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent No. 493,293, dated March 14, 1893. Application ned March 14, 1892. seria No. 424.784. (No modem .To all whom it may concern:

Be it known that I, ANTON PRIER, of Kansas City, ackson county, Missouri, have invented certain new and useful Improvements in Illuminating Vapor-Burners, of which thefollowing is a full, clear, and exact description, ret'- erence being had to the accompanying drawings, forming a part hereof.

My invention relates to vapor-burners which are used for illuminating purposes.

The objects of myinvention are to produce an illuminating burner which shall be simple and inexpensive in construction, and entirely automatic in operation, and which shall be capable of thoroughly and economically vaporizing and consuming gasoline and kindred inflammable oils, and at the same time produce the maximum amount of candle-power of illuminating flame from the vaporized oil.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described and claimed.

In order that 4my invention may be fully understood,I will proceed to describe itwith reference to the accompanying drawings,'in

which:

Figure l is a central vertical longitudinal section of the burner and its supply and feed pipes. Fig. 2 is a horizontal section of the same, on the line 6-6 of Fig. 1. Fig. 3 is a transverse vertical section of the inlet-valve, on the line 7-7 of Fig. 1. Fig.4 isadetached perspective view of the retort or generator casing or shell. Fig. 4a is an inverted ,or under side perspective view of the same. Fig. 5 is a detached perspective view of the burnertip. Fig. 6 is a detached perspective view of the combined igniting cup and burnervalve operating-wheel.

In said drawings 3 designates the supply pipe, one end of which is designed to be connected to a suitable reservoir for gasoline or other inflammable oil, and the lower or opposite end of this supply-pipe 3 is externally screw-threaded to enter the internally screwthreaded socket 4 of an inlet-valve casing 5. This casing 5 is also formed with an internally screw-threaded socket 6 into which is inserted one end of an externally screw-threaded feed-pipe '7; the said socket 6 preferably exn tending oppositely from the socket 4, as shown.

The body-portion of this casing or shell' 5 is formed with a vertical valve-chamber 8, the upper end or seat of which is of tapered or conical form, as shown, while the lower end of said chamber communicateswith an internally screw-threaded socket 9 which is pendent from the under side of the casing or shell 5.

Within the valve-chamber S works an inlet needle-valve 10 which is of tapered or conical form to lit the correspondingly shaped upper end or seat of the valve-chamber 8. The lower part of the stem of this inlet-valve 10 is externally screw-threaded, as at 11, to engage the internal screw-threads of the pendent socket 9 of the uvalve-casing, while the lower extremity of said stem is provided with a knob or finger-piece 12 by means of which the valvestem is turned to raise and lower and consequently close and open the inlet-valve.

13 designates a channel which extends longitudinally or axially through one end of the shell or casing 5; the outer end of said channel communicating with the inner end of the cavity of the socket LI and the inner end of the channel communicating with the middle of the valve-chamber 8.

14 designates a second longitudinal channel which extends obliquely downward and outward from the upper end of the valve-chamber 8 to the inner end of the cavity of the socket 6; the inner end of the channel 14 communicating with the chamber 8 at one side of its upper end, and the outer end of said channel communicating with the cavity of the socket 6 above thc center of the inner end thereof. The opposite end of the feed-pipe 7 from that which is inserted into the socket 6 is externally screw-threaded to enter the internally screw-threaded rear end of the vapor generator 15 of the burner, as shown. Thls vapor generator 15 is 0f cylindrical form and is formed integrally with a bracket 18 from which extends obliquely downward and forward a feed-tube 16 for the burner. The channel 17 of the feed-tube 16 extends axially or longitudinally of the tube and opens into the front end of the cavity of the generator 15, at a point below the axial center of said cavity, as shown. The upper end of the feedtube 16 is united integrally with the under side of the horizontal bracket 18 which is formed integrally with the under side of the ICO generator 15, and which extends longitudinally of said generator. The front end of this bracket protrudes beyond the frontend of the generator and the upper portion of the channel 17 ot' the feed-tube 16 passes obliquely through said bracket 18 transversely and about midwayof the length of the latter. This feed-tube 16 extends obliquely downward and forward from its pointof union with the bracket 18 as above stated and at its lower end said feed-tube is integrally united to the base 19 of the vertical burner-tube 20; the lower end of the channel 17 of the feedtube 16 being closed preferably by a plug 21, necessitated by the boring of said channel. The base 19 of the burner-tube 2O is formed with a transverse channel 22, the outer end of which is closed preferably by a plug 23, necessitated by the boring of the channel 22, and said channel communicating at its rear end with the lower end of the channel 17 of the feed-tube 16. The base 19 of the burnertube 20 is also formed with a vertical channel 24, the lower part of which is internally screwthreaded and opens out of the lower end of the base 19. The channel 22 communicates with the upper part of the channel 24 and the upper end of said channel 24 is of tapered or conical form, as at 25, so as to form a seat for the needle-Valve of the burner.

26 designates the stem of the needle-valve of the burner, said stem being externally screwthreaded to engage the internally screw-threaded lower part of the channel 24 of the burner-tube 20. The upper end of this stem 26 is tapered or formed conically, as at 27, s0 as to constitute the needle-valve of the burner, and so also as to properly register with the conical valve-seat 25 before described. At its lower end-portion the stem 26 carries an operating-wheel 28 for rotating the valve 26; the lower part of said stem 26 passing through the hub 29 of said wheel. At its lower extremity, the stern 26 is formed with an angular portion 30 to receive a Wrench or a similar implement, for turning the stem in the event of said stem becoming clogged in its channel 24 so that it cannot be rotated readily by the wheel 28. It is to be understood that the wheel 28 serves also as an igniting-cup for the burner, as hereinafter explained, and for this purpose the upper surface of the wheel is formed concave, as at 31 to receive aquantit-y of oil which is to be ignited for starting the generating action of the burner. The burner-tube 2O is preferably of cylindrical form, as shown, and is integrally united at its upper end to the outer end of the bracket 18. Through the sides of the said tube, justabove the base 19 thereof, are formed a number of openings 32 which serve to admit air within the burner-tube for supporting the combustion of the vaporized oil, as hereinafter more fully described.

33 designates the tip of the burner, said tip being preferably ofcylindrical form as shown, and having a cross-slit 34 at its upper end to ings 36, the purpose of said openings being to permit jets of ignited vapor to be injected intothe Vretort-shell or casing, hereinafter described, and thus automatically support vaporization of the oil.

37 designates the shell or casing of the retort, said shell or casing being of elongated cylindrical form and placed horizontally and being also of greater diameter than the generator 15. The rear end of this retort shell or casing 37 is formed with an opening 38 through which extends the front end of the feed-pipe 7, and the under side of said shell is formed, at its front end, with a recess 39 which extends longitudinally of the shell or casing, and which opens out at the front end of said shell or casing. This recess 39 corresponds in length with the bracket 18 so that said bracket is closely embraced by the margins of said casing. At its upper side, at a point directly opposite the recess39, the shell or casing 37 is formed with a second and much shorter longitudinal recess 4:0 which also opens out at the front endof the shell or casing 37. This recess 40, as well as the outer part of the recess 39, receives the inner side of the tip 33; the margins of said recesses 39 and 40 and of the intermediate end-portions of the shell or casing 37, closely embracing the inner side of the tip, as shown.

It will be understood that in order to start the above described burner into operation, the valves 10, and 27 are opened and a small quantity of oil is allowed to flow out of the air-inlet openings 32 and downward into the cavity of the wheel 28, and is there ignited. The dame frornthe oil in the cavity of the wheel 28 envelops the base 19'ot` the burnertube 20 and thelower portion of the feed-tube 16 and starts the vaporizing action ofthe burner. As the vapor is emitted from the tip 33 after the burner iswell started in operation it is ignited and forms an illuminating dame of great power, and at the same time, the vapor escaping from the openings 36 of the tip 33 is forced into the retort casing or shell 37. These flames envelop the generator 15, and thus continue the vaporization of the oil in said generator; this vaporizing action continuing as long as the oil-supply lasts and the Valves 10 and 27 remain open.

Freni the above description it will be seen that the burner is simple, durable and inexpensive in construction, and also entirely automatic in its operation, and that itis of high` illuminating candle-power.
